L_LTDOC_API L_INT L_DocSetUserDictionary(hDoc, pUDOpts , bCreateUD)

L_HDOC hDoc;	/* handle to the OCR document */
pUSERDICTIONARY pUDOpts;	/* pointer to USERDICTIONARY */
L_BOOL bCreateUD;	/* flag */

Sets the User dictionary and its default section for the checking subsystem.

Parameter	Description
hDoc	Handle to the OCR document.
pUDOpts	Pointer to a USERDICTIONARY structure which contains the user dictionary to be set.
bCreateUD	Flag to determine function behavior. Valid values as follows:
	Value	Meaning
	TRUE	Creates new user dictionary in memory
	FALSE	Saves the current user dictionary into the file indicated in the pUDOpts parameter.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Specifies a User dictionary and its default section for the checking subsystem.

This function can also be used to initiate the creation of a new, empty User dictionary in memory.

To disable a previously enabled User dictionary, pass TRUE for bCreateUD when calling L_DocSetUserDictionary.

When creating a new, empty User dictionary, pass TRUE for bCreateUD.

If you save a user dictionary by calling this function with bCreateUD set to FALSE the user dictionary is saved to the file specified in pUDOpts. If you later want to set the user dictionary to use this file, call L_DocSetUserDictionary with the name of the file that contains the user dictionary set in the pUDOpts parameter of this function and pass FALSE for the bCreateUD parameter.
